A method of monitoring a marine seismic source array comprises, consequent to actuation of a seismic source array (14), making a near-field measurement of seismic energy emitted by the seismic source array (14), using at least one near field sensor (15) and also acquiring seismic data using at least one seismic receiver (18). The far-field signature of the source array at one or more of the receiver location(s) is estimated from the near-field measurements of the emitted seismic energy, and this is compared with seismic data acquired at the receiver(s). This provides an indication of whether the source array and the method for predicting far-field signatures are operating correctly. |
